Removing someone else's comments!

I'm sure this must be covered somewhere but I can't figure out how to get rid of someone's inappropriate comments on my Instructable. Any help is appreciated. I went to the comment, clicked flag. Marked as inappropriate. Does it just take a few days? I don't want my project to be a platform for a loudmouth that isn't even speaking about the project.

Hi, I've noticed a lot of recent comments on one of my I'bles that have URLs in them and look like advertisements. I mean, something presumably intelligent took time to write more than just a URL in the comment but it still seems to be a shill. Is this flaggable or just let it go?
